Abstract
This work discusses the additive manufacturing of an axicon lens using cyclic olefin copolymer (TOPAS), and its characterization between 100 GHz and 300 GHz. The proposed manufacturing process followed by dip-coating post-processing provides an improved surface finish. Additionally, the terahertz output of the lens remains intact over the entire frequency range.
